OP284 and ADA4897-1 and maximum PCB driving distance

Hello experts

Question and appreciate your advise:

For a standard PCB (FR4, 4 layers 1.6mm pcb thickness, track of 0.254mm, with ground plane on the 2nd layer). point-to-point. and assuming termination is good. Signal source frequency is approx 1khz to 500Khz.

(a) can these amplifiers (OP284 and ADA4897-1) drive a distance of 12 to 15 inches long when they are configured as a unity gain buffer driver.

(b) if not, what would the maximum driving capable distance be.

Thanks and Regards,
